摘要
目的 对比分析普通 CT与螺旋 CT(SCT)对胰腺肿瘤患者的检查结果 ,探讨胰腺癌诊断及手术可切除性问题 ,提高对早期诊断的认识 .方法 将 38例经临床和病理检查确诊的胰腺癌患者分为普通 CT组 2 3例 ,SCT组 15例 .分别观察肝脏、腹腔、淋巴结转移和邻近大血管受侵犯情况 .两组患者检查结果作对比 ,手术切除病例与术前 CT检查结果作对比 .结果 CT检查结果比较 :SCT组肿瘤侵犯转移征象检出率明显高于 CT组 (P<0 .0 1) .CT检查与手术结果比较 :术前判断可切除肿瘤的准确率 SCT(88% )组明显高于 CT(6 0 % )组 .结论 比较研究发现 SCT较普通 CT分辨率高 ,能够更清楚地表现胰腺肿瘤的形态特征及其周围征象 ,能够反映胰腺癌侵犯转移征象 ,从而更准确地预测肿瘤病灶的可切除性 .
AIM To compare and to analyze the results of examination of patients with pancreatic cancer by general CT (CT) and spiral CT (SCT), and to discuss the problems related to the diagnosis and respectability of pancreatic cancer in order to achieve early recognition and diagnosis. METHODS State of involvement of the liver, peritoneal cavity, lymph nodes and adjacent vascular structures were observed in 38 patients with pancreatic cancers, among whom 23 were examined by CT and 15 by SCT. The results of both CT and SCT groups were compared and the status of the tumor at surgical resection were compared with CT images before operation. RESULTS Positive rate of detection of signs of tumor invasion by SCT was higher than those by CT ( P < 0.01 ). The accurate rate of detecting preoperatively resectable tumor by SCT was remarkably higher than by CT. CONCLUSION Spiral CT may have a higher resolution rate than general CT. SCT could not only demonstrate distinct morphological peculiarities of pancreatic cancer and the surrounding structures better than CT but also reflect the signs of invasion and metastasis, thereby predicting more accurately the resectability of the tumor.
